The worldwide network’s performance was very strong in all regions of the world, the firm said. Member firms in the Americas and Asia grew at 24% with 20% revenue growth. In the Europe, Middle East & Africa region GT firms grew at 16% year on year.

David McDonnell, chief executive of Grant Thornton International, said: ‘These results show a continuing very strong performance by member firms around the world, even though it was a year which saw overall economic performance falter in some areas. The member firm in the US, the world’s major economy, showed outstanding growth with a 30% increase in revenues.’
